In recent years by building external wall thermal insulation materials ignited the fire accidents, building exterior insulation system of fire safety by the attention of the relevant state ministries and commissions.

The Ministry of Public Security issued the civil building exterior insulation system and external decoration fireproof Interim Provisions "file 2009 [46], and 2011 [65]," on further clarify civil building exterior insulation materials fire supervision and management of the relevant requirements of the notice "document, of residential and public buildings, glass curtain wall building exterior wall thermal insulation material has made very clear request, clearly pointed out that building insulation materials must use A-class non combustible material, resulting in building external wall thermal insulation A-class non combustible insulation materials has become an inevitable trend.

Cement foam insulation board is a non combustible material, non-toxic, environmental protection, low carbon is a new type of energy saving and waste heat preservation material, which is advocated by the state. Is currently the wall insulation and fire isolation with the most ideal material, in line with the national building energy conservation promotion requirements.

January 2014 Wuhan Hubei urban and rural construction committee requirements in the city's civil building wall, roof, floor insulation project, the design and use of the prohibition of the design and use of thermal insulation mortar products.
